Description

Technical Field

[0001] This utility model belongs to the field of well logging equipment technology, and in particular relates to a petroleum well logging bridle. Background Technology

[0002] Well logging equipment is of great significance to oil exploration and development. Applying logging equipment and technology to mines can effectively collect various physical information from the underground environment, such as force, heat, and nuclear data. Analyzing this data can effectively interpret the thickness and location of oil and gas layers within the oilfield, and can also determine some performance parameters related to extraction. Well logging bridles are a type of well logging equipment used to connect cables and downhole instruments; they allow for quick connection and disconnection while ensuring good continuity and insulation between the cable core and the instrument wires.

[0003] In existing technologies, during well logging, the connection of the bridle is prone to loosening during measurement and shaking. At the same time, the cable is prone to wear and breakage during shaking, causing the instrument to fall into the oil well, affecting the detection effect and causing economic losses.
